1 Preface and general instructions
The various bed systems from Hermann Bock meet special requirements for the use in
care and treatment facilities as well as for home care. Reliable functionality and a long
product life make each bed particularly valuable. Our beds need little maintenance with
proper operation and care. Each bed from Hermann Bock must pass quality testing in a
final inspection before it is shipped anywhere. The beds are manufactured according to
the current standards and compliant with the statutory requirements for medically used
beds, and tested accordingly.
The nursing care beds comply with the EN 60601-2-52 standard. The electrical building
components comply with safety standard EN 60601-1 for medical devices. Comfort beds
that can be converted into full-fledged nursing care beds are medical devices, and are to
be assigned to Class 1.
These standards divide the beds in five different areas of use:
1. Intensive care in a hospital; intensive care bed
2. Short-term care in a hospital or other medical facility; patient bed in the hospital
3. Long-term care in medical environment; stationary nursing care bed
4. Care at home, pure so-called “HomeCare bed”
5. Home-care nursing service
1.1 Intended purpose
The comfort/nursing care bed is suitable for persons in the
need of care (adults) who are at least 146 cm tall. The person's
weight must not exceed 185 kg and must be over 40 kg. The
body mass index (BMI = weight of the person (kg) / body height
of the person (m)2) must be greater than or equal to 17.
The stellar may be used as a nursing care bed in homes for the elderly or nursing homes
and rehabilitation facilities. It is used to alleviate a disability and/or to facilitate the lives
of people who are in need of care or to make the work of their caregivers easier. Accordingly, the nursing care beds are designed to be used for the application environments 3 to
5. Furthermore, the stellar as a comfort bed was also designed as a convenient solution
for the home care of frail and elderly people, as well as for the home care of people with
disabilities. Accordingly, the comfort bed described below is intended for the application
environment 4.
Any other use is considered improper and is excluded from a possible liability claim.
The Trendelenburg function may not be used for this comfort / nursing care bed.
5
The comfort/nursing care bed is not suitable for the use in hospitals. It is also not designed
to transport patients. The comfort/nursing care bed can only be moved within the patient's room - even during a patient positioning - for example, for cleaning or to provide a
better access to the patient.
The comfort/nursing care bed is suitable for the re-use. Please observe the instructions
for cleaning, care and disinfection in these assembly and operation manual. Special attention must also be paid to the information regarding the inspections.
Attention: The comfort/nursing care bed has no special connection options for an potential equalisation. Electrical medical devices connected to the patient intravascular or intracardiac may not be used. The operator of the medical products has to ensure that the
combination of the equipment meets the requirements of EN 60601-1.
This user manual contains safety instructions. All persons working with the comfort/nursing care beds must be acquainted with the contents of these instructions. Improper operation can result in personal injuries.
1.2 Definition of person groups
Operator
Operators (e.g. medical supply stores, specialist dealers, facilities and cost units) include
all physical or juridical persons, who use the comfort/nursing care bed, or have the comfort/nursing care bed used upon their order. The briefing on the use of the product shall
generally be conducted by the operator.
User
Users are persons whose training, experience or briefing on the product allows them to
operate the comfort/nursing care bed or carry out works on it. The user is able to recognize possible hazards and/or to avoid them and to assess the health condition of the patient.
Patient/resident
Person with one or more disabilities, one or more activity restrictions, one or more participation restrictions or a combination thereof.
Qualified personnel
Employees of the operator are referred to as qualified personnel. They are entitled to
deliver the comfort/nursing care bed, assemble, dismantle and transport it, on the basis
of their training or instructions. Besides knowing how to operate, mount and demount
the comfort/nursing care bed, these persons must be instructed according to the guidelines concerning the cleaning and disinfection of the comfort/nursing care bed.

1.3 Safety instructions
The intended use/operation of all moving parts is as important for the safety of the person
in need of care as well as for the relatives and the caregivers/nursing staff to avoid potentially dangerous situations. This requires the correct installation and operation of the comfort/nursing care bed. The individual physique of the person in need of care as well as type
and the extent of their disability must be taken into account by all means when operating
the comfort/nursing care bed.
Avoid dangers, accidental motor adjustments and incorrect operation by using the disabling function. When the operator, e.g. the nursing staff/caregivers or the care providing
relative leaves the room, the entire operating functions of the comfort/nursing care bed
should be disabled via the key on the hand control. This is achieved by operating the key
of the hand control. First, lower the lying surface to the lowest position and activate the
lock function with a twist of the key, located in the key lock on the backside. Remove the
key and check the function of the hand control for safety reasons. Make sure that it is
indeed locked.
These recommendations apply particularly:
– if the person in need of care cannot operate the hand control safely due to
certain disabilities;
– if the person in need of care or the caregivers could be at risk due to those
accidental adjustments;
– if the side rails are in a raised position and there could be danger of trapping
and crushing,
– if children are unsupervised in the room with the comfort/nursing care bed.
Always make sure that the hand control (when not in use) is securely hooked in the support hook at the comfort/nursing care bed and cannot drop.
As a general rule, the comfort/nursing care bed should be operated by instructed nursing
staff/caregivers, relatives or in attendance of instructed persons.
When adjusting the lying surface, it is particularly important to ensure that no limbs are
placed within the adjustment range of the side rails. If the side rails are adjusted, pay
attention to the correct lying position of the person in need of care.
Prior to making any electrical adjustment, it should, as a general rule, be made sure that
no limbs are positioned in the adjustment range between the chassis and the head or foot
part, especially that there are no persons or animals in the area between the floor and the
raised lying surface. In case of a double bed, it must also be ensured that there are no
limbs between the two lying surfaces. Danger of being crushed is particularly high in these
7
areas. Always pay attention to objects that are near or even below the comfort/nursing
care bed. This can lead to damages.
The permitted person’s weight depends on the total weight of the equipment that has
been mounted to the bed (mattresses and other electronic medical devices). For safe
working load, please refer to the type plate on the lying surface frame of the bed.
1.4 Service life / warranty
This comfort/nursing care bed was developed, designed and manufactured for a safe operation over a long period of time. With proper operation and maintenance, this comfort/nursing care bed has an expected service life of 15 to 20 years. The service life depends on operating conditions and frequency.
Attention: Unauthorised technical changes to the product voids all warranty claims.
This product is not approved for the North American market, particularly not for the
United States of America (USA). Distribution and use of the comfort/nursing care bed in
these markets, including through third parties, is prohibited by the manufacturer.
1.5 Requirements for the installation location
The company Hermann Bock GmbH is not liable for damages which might arise from the
daily usage on the floor.
To avoid floor indentations, floor should correspond to the recommendations of the FEB
- Fachverband der Hersteller elastischer Bodenbeläge e. V. (Association of Elastic Floor
Coverings Manufacturers). To do this, the technical information FEB No. 3 can be referenced.
Hazard note from Bock
Simultaneous use of electrical appliances particularly in the vicinity of the operational comfort/nursing care bed may result in small electromagnetic interactions of these electric devices,
e.g. static noise in the radio. In such rare events, increase the distance of the devices. Do not use
the same socket or temporarily switch off the interference source and/or the disturbing or disturbed device.
If the comfort / nursing care bed is operated with electrical or medical devices contrary to its
intended purpose, the functions of the comfort / nursing care bed must first be deactivated for
the duration of use via the integrated locking function in the hand control.

2 General description of the functions
Construction design and function
Corrosion protection
The Hermann Bock GmbH comfort/nursing care beds are developed and constructed in
such a way that they can function for a long time and safely. For this reason, all materials
that may corrode are protected accordingly. All metal parts are equipped with a surface
protection. The steel parts are either galvanised or stove-enamelled with a PES powder
coating and the aluminium profiles are anodised.
The lying surface with 4 function areas
The lying surface consists as standard of a slatted comfort frame (can alternatively be fitted with aluminium slats or special suspension systems) and is divided into four functional
areas: Backrest, solid seat, upper and lower leg rest.
The comprehensive lying surface frame is welded from a steel/aluminium tube. The steel
tubes are stove-enamelled with a PES-powder coating. The electric variable height adjustment of the lying surface is carried out with protective low-voltage DC motors (29 to 35V),
and controlled with the smooth keys of the hand controller. The backrest can be adjusted
electrically. The leg part consists of a foot support that is divided into two parts. With a
touch of a button on the hand control, each individual position can be adjusted continuously. In case of a power failure the back part that can be lowered by loosening the tube
clip.
The chassis
The height adjustment of the comfort/nursing care bed is performed through a base
frame with two individual drives. The surface of the tubular steel structure is stove-enamelled with a PES-powder coating.
1 long back part
2 fixed seat part
3 upper leg rest
4 lower leg rest
11
The side rail
Each comfort/nursing care bed can be equipped on both sides with two side rails at a
special safety height. The side rails can be lifted and lowered. Depending on the model,
shorter or longer divided side rail variations are available. The side rails can be retrofitted
on the stellar comfort/nursing care bed.
Operating the telescopic split side rails (optional)
Each side rail element can be adjusted independently from the rest
of the side rail parts. The release buttons for adjustment are on the
bottom of the telescopic post and on the top of the appropriate end
panel of the comfort/nursing care beds, right next to the metal
guides for the side guard rail bars.
To lower the side rail element, hold the upper knob (1) of the middle
post with one hand, lift it up slightly, and with the other hand press
the release button (2) on the middle post in the inner direction.
The side rail opens at the corresponding place and can be easily lowered downwards as far as it will go (3). The side rail is now diagonal.
To also lower the other side, please hold the side rail on the side of
the end panel at the gripping groove (4), and slowly raise the side
rail somewhat. Now, you can fully press the release button (5) and
slowly lower the side rail.
Please observe:
Be sure to raise the side rail slightly, and only then press
the release button! Failure to do so will result in damage to the release.
The side rail is now in the lowered position.
If the side rail element should be placed in the top position to aid in
fall prevention, reach with both hands in the centre of the gripping
groove (6) in the upper side guard rail, and pull it upwards until you
hear it click into place at both ends. The side rail is now in a pulledup position.

Hazard note from Bock
Use only original Bock side rails, which are available as accessories for every comfort / nursing
care bed.
Use only technically flawless and non-damaged side rails with the permissible gap dimensions.
Make sure that the side rails are engaged securely.
Before installation of the side rail and each new use, inspect all mechanical parts on the bed
frame, and all parts of the side rails, and all parts which secure the side rails, for any possible
damages.
The operation of the side rail should be done with great care. Fingers can be quickly pinched
between the longitudinal pieces.

3 Electric parts
3.1 The drive unit
The drive unit consists of individual drives for the electrical adjustment of the back and
leg rest part. The level adjustment is performed with two individual drives that are attached to the chassis. The adjustment range of these individual drives is determined via
Hall sensors. The motors and the hand control are connected to the inner control box. The
internal control box includes a switch box with a rectifier in which the input voltage is
converted into a protective low voltage of max. 29 VDC direct current. The motors, controller and the hand control function with this non-hazardous low protective voltage. The
cables are double-insulated and the mains plug has a primary fuse.
A power adjustment provides constant function speed. Therefore, the safety functions
comply with protection class II and the moisture barrier protection type IPX4.
The maximum duty cycle is specified on the (type plate) of the comfort/nursing care bed.
For example, 10% duty cycle (2 min. ON / 18 min. OFF) means that any electronic adjustment can be performed for a max. of 2 minutes within a timeframe of 20 minutes (protection against overheating).
If the maximum setting time of two minutes is exceeded by two minutes (e.g. someone
plays continuously with the hand control), which could lead to overheating of the controller or drives, the thermal fuse immediately shuts off the power supply to the comfort/nursing care bed. After a cooling time of approx. one hour, the power supply in the
controller is automatically restored.
3.2 Caution: Electric drive
The electrically operated comfort/nursing care bed enables the persons in the need of
care to support the recovery process psychologically and physically and at the same time
relieve pain through its various functions. As medical products, electrically operated comfort/nursing care beds require special care with regard to constant safety checks. This includes a safety-conscious handling of the comfort/nursing care bed, daily inspection of
electrical equipment and a proper maintenance and cleaning.
To prevent damages to the cables, wiring should be conducted outside of the area in
which damages could be caused. Furthermore, avoid touching the sharp parts. To prevent
injury through an electric shock, avoid the possibilities of too high contact voltages. These
circumstances may especially be the case if the power cable is damaged, if inadmissible
and excessive leakage currents exist, or if liquid was spilled into the motor housing, e.g.
during improper cleaning. This damage can cause malfunction of the controller, which
could result in unwanted movements of single bed elements, posing a risk of injury for the
operator and the person in need of care.
15
3.3 Drives
Hermann Bock GmbH equips comfort/nursing care beds with drive systems from the company DewertOkin GmbH.
Each drive consists always of four main components.
– Housing
– Motor
– Gear
- Spindle with nut
The housing principle of the individual drive guarantees the permanent function of all
drive components. Through a detailed interior structure, the construction of the housing
interior creates an essential prerequisite for the precise integration of the drive technology, as well as a trouble-free assembly/disassembly.
3.4 The controller
Controller comfort/nursing care bed stellar - front side
The stellar comfort/nursing care bed is equipped with a controller system from DewertOkin GmbH. Four drives can be connected to the controller (sockets 4, 5, 6 and 7). The
colour coding can be found in chapter 4 "Assembly and operation". Y-cabling is connected
to the connection socket for the hand control (socket 2). Make sure that a dummy plug is
fitted to the connection for the fifth motor (socket 3) and that a red jumper plug is plugged
into the connection for a second controller (socket 1).
16
Controller stellar comfort/nursing care bed - back side
Connections are also provided on the back of the control box. A further control box (socket
8) for the ambient lighting, if available, is plugged in at this side.
3.5 The hand control
The hand control is equipped with a built-in locking device, which allows the caregivers to
lock the hand switch via a key completely or partially for its operation.
The lockable hand control, first-fault protected
The base functions can be controlled through the ten operation keys on the hand control.
The three icons in the centre indicate a special function that can be carried out by simultaneous applying finger pressure on the adjacent keys. The individual keys are marked
with corresponding symbols. The servomotors run until as long as a corresponding key is
pressed and held. A coiled cable allows the necessary freedom of movement while operating.
With the rear-mounted suspension unit, the hand control can be attached to the side rail
- particularly when cleaning and during the maintenance of the comfort/nursing care bed.
Thus, a possible disruptive position of the hand control can be avoided by simply attaching
it to any preferred spot on the comfort/nursing care bed.
Hazard note from Bock
Do not exceed the maximum duty cycle of 2 minutes. Observe a subsequent break of at least
18 minutes by all means.

4.2 stellar
A comfort/nursing care bed for all circumstances that unifies technology and comfort.
Technically perfected down to the last detail: The stellar can be equipped with various
lighting systems. In addition, USB connections and 230V sockets can be installed in the
comfort bed. The side rails can be retrofitted. This comfort/nursing care bed provides a
high degree of comfort to frail people, persons in the need of care and people with disabilities, thus facilitating an optimal care through a high lying comfort and an easy operation.
- The stellar is not suitable for hospital use.
- The comfort/nursing care bed stellar is not suitable for the transport of the pa-
tient. The comfort/nursing care beds may only be moved for cleaning purposes
inside the patient’s room or to allow access to the patient.
- The comfort/nursing care bed is suitable for persons in the need of care (adults)
who are at least 146 cm tall. The person's weight must not exceed 185 kg and
must be over 40 kg. The body mass index (BMI) must be greater than or equal
to 17.
- Under certain circumstances the stellar can be used (if necessary) for medical
purposes with other electric medical equipment (e.g. suction devices, ultrasonic
humidifier, food systems, anti-bedsore systems, oxygen concentrators and similar devices). In this event, disable all bed functions for the duration of the application via the integrated disabling function.
Attention: The comfort/nursing care bed has no special connection options for a potential
equalisation. Electrical medical devices connected to the patient intravascular or intracardiac may not be used. The operator of the medical products has to ensure that the combination of the equipment meets the requirements of EN 60601-1.
24
stellar becomes operational
Remove all packaging from the comfort/nursing care bed and place the chassis
on a free level surface.
.
Place the cross beam (1) including the controller on the chassis (2).
Pay attention to the head and leg end.
On the left side of the Fig. you can see the
mountings for an end piece, and these are
to be placed in the head area. On one side
of the cross beam, a receiver is visible under the sheet metal cladding. This must
also be aligned on the head side.
Place the cross beam on the chassis so that
the holes are on top of each other. Fasten
the lying surface with the 4 screws (3) supplied (cylinder head screws M8x55) and
the 4 nuts.
Place the lying surface on the cross beam.
Pay attention to the head and leg end.
On the left side of the Fig. you can see the
mountings for an end piece, and these
must be placed in the head area of the lying
surface.
The strips of the lying surface can be removed for the assembly.
Slide the lying surface on the chassis so
that the holes are aligned on top of each
25
other. Fasten the lying surface with the 4
screws supplied (cylinder head screws
M8x50) and the 4 nuts.
Now the cables of the control actuating device motors can be safely laid underneath
the lying surface up to the control box. To simplify the cable routing, you can remove
some of the panels from the lying surface frame. To access the controller, remove the
middle cover of the controller (A) by loosening the screws (B) from the cross beam. The
cables must be inserted from below between the two tubes (C) of the cross beam. Ensure that the cables cannot be not clamped or damaged in any way.
Cable routing from the head part motor (D) and foot part motor (E) of the lying surface
to the controller.
26
When laying the cable, use the clip (F) to fix
the cable to the head or foot lifting unit.
Ensure that the clip is positioned in front of
the controller cover. In addition, the cable
behind the clip must be long enough to
route it under the cross beam all the way
to the controller.
Pin assignment of the controller for the comfort/nursing care bed stellar:
1. Green: Jumper
2. Red: Y-cable
3. White: Stopper (free)
4. White: Scissor drive - foot
5. Blue: Scissor drive - head
6. Yellow: foot part of lying surface
7. Black: lying surface back part
27
Please also refer to the description of the controller in chapter 3.
After all plugs have been connected to the controller, you may connect the supplied
cover cap to the controller so that the connectors are securely fastened.
The hand control is connected to a separate control box (G) located in the
head area. To do this, a further part of
the cover must be removed (as described above for points A and B). The
hand control is then plugged into the
hand control box. Use the plug socket
which points in the direction of the
(head) end piece.
After all plugs have been connected to
the hand control box, you may connect
the supplied cover cap to the controller
so that the connectors are securely fastened.
Attention: If your comfort bed is factory-equipped with a floor lighting, you must insert
the hand control into the free socket of one of the two floor lighting units. The floor
lighting is already mounted on the lying surface frame. In this case, the plug of the floor
lighting must be inserted into the socket for the hand control (red mark) on the
controller. Ensure that all sockets are subsequently covered with the locking caps, in
order to guarantee the protection class requirements.
Route the power cable in the middle across
the frame of the chassis, all the way to the
head end piece. There, please screw on the
cable with the help of the strain relief.
28
Now, attach the mattress brackets using
the supplied self-tapping screws, if these
were not factory-installed (depending on
shipping method of the comfort/nursing
care bed).
Subsequently, raise the chassis for the further assembly. To do this, connect the
mains supply line feeder from the controller to a power source, and then move the
comfort/nursing care bed upwards. The
comfort/nursing care bed can then be disconnected from the power supply again.
Apply the parking brake to the castors to
prevent unintentional movement of the
comfort/nursing care bed.
Assembly of panels and padding
Push the head panel (1) with the aluminium profiles first into the lying surface.
Make sure that the panel is pushed all the
way to the lying surface and that there is
no gap. The grub screws (2) can now be
tightened on both sides on the underside
of the lying surface to fasten the panel.
29
The foot side padded panel (3) is mounted
in the same way.
Next, the side panels (4) are attached to
the lying surface. For this purpose, the
panel is placed above the aluminium longitudinal beam (5). The panel should be set
at a slight angle so that the brackets can
pass the aluminium longitudinal beam. The
panel must first be lowered in direction A
and can then be moved in direction B if the
brackets are correctly seated on the aluminium longitudinal beam.
The side panel should then be pushed as
far as possible towards the foot area.
The side panel must then be screwed from
firmly from below. The same grub screws
as in point (2) are used for this purpose.
These are screwed into the holders (6) of
the side panel and fastened to the lying
surface. Fasten the side panel with 6 grub
screws (7) .
30
The same procedure is then repeated for
the other side so that the panels are completely mounted on the lying surface.
The chassis of the stellar comfort/nursing
care bed is also fitted with a panel covering. The first step here is to mount the side
panels. These side panels are equipped
with two different mountings. The U brackets (8) can be attached to the mountings
(9) on the chassis provided for this purpose. The panel must thereby be pushed
down as far as possible.
Attention: The unneeded long mounting,
shown here in the right Fig. is pointing to
the foot end!
The second panel can then be mounted on
the chassis.
The last panel (10) for the chassis is inserted on the foot side. There are two black
wedges (11) located on this panel, which
are used for fixing and connecting the side
panels. Slide the wedges evenly over the
holders (12) provided for this purpose, and
push the panel downwards in the direction
of the arrow.
Ensure that all panel are positioned at the
same height. If this is not the case, the
screws on the brackets can be loosened
slightly, and the panels can be brought into
the appropriate positions. Afterwards,
tighten the screws of the brackets again.
31
Finally, the head end piece (13) must be
mounted. This is inserted via two wedges
(14), as was the case with the panel before
(the double bed has four wedges). The
wedges are inserted into the holders (15)
on the head side. Make sure that the mains
supply line feeder is routed out under the
head end piece. The head end piece must
thereby be pushed down as far as possible.
You can now plug the mains supply line
feeder of the controller and other accessories into the multiple socket (16) of the end
piece.
Check all screw connections again before using the comfort/nursing care bed.
IMPORTANT!
Please perform a reset of all the motors, before putting the comfort/nursing care bed into
operation. This procedure is described in chapter 3 "The hand control".
Hazard note from Bock
The comfort/nursing care beds are not suitable for transporting the patient. The comfort/nurs-
ing care beds may only be moved for cleaning purposes inside the patient’s room or to allow
access to the patient.
32
4.3 Mounting the side rails
The comfort/nursing care bed stellar can be equipped
with side rails. The comfort/nursing care bed should be
moved to its uppermost position (1) to enable the installation of the side rails. This considerably simplifies the assembly.
In order to install the side rails, the side padding must be
removed. This is attached to the lying surface at three
points (2).
Remove the six grub screws (3) that secure the side panel
to the lying surface. This requires a size 4 Allen key. The
screws are located underneath the lying surface.
When all screws have been removed, the side panels (4)
can be removed from the lying surface. To do this, grip
the lower edge of the panel and pull it away from the
comfort/nursing care bed. The panel can then be lifted
upwards from the aluminium longitudinal beam.
Now the telescopic posts can be mounted on the lying
surface. To do this, hang the telescopic post with the
bracket into the aluminium longitudinal beam. This telescopic post must then be pushed towards the end of the
lying surface (5). Make sure that this is not pushed beyond the length of the lying surface. The lying surface
must still be visible when viewed from the front.
33
The telescopic post must now be fastened. For this, the
supplied M8 grub screws must be screwed into the two
threaded holes (6). Tighten the grub screws evenly so that
the telescopic post has a firm hold.
Make sure that the distance between the
telescopic post and end piece is smaller than 60mm.
The side rail can now be attached onto the telescopic
post. To do this, slide the opening of the plastic cap over
the bracket of the telescopic post. Make sure that the
side rails are correctly aligned with the brackets (see illustration)! The opening in the plastic parts points downwards. The lettering ". bock ´´´" should be legible on the
plastic parts.
Proper view from below
The hole in the plastic parts of the side rails must now be
above the hole in the telescopic posts. If this is the case,
the sleeve nut (9) can be inserted through the side rail.
The flat screw (8) can then be inserted and tightened
from the other side.
Ensure that all screws (10) are present and fastened handtight. If this is not the case, there is a risk that the side
rails will fall out during the first adjustment.
34
The second telescopic post must then be mounted. In this
case another single telescopic post (11) was selected. Alternatively, this can also be a double telescopic post. Push
the side rails with their plastic parts together as far as
possible. Now the telescopic post can be placed on the aluminium longitudinal beam. Push the telescopic post into
the openings of the plastic caps as before. Afterwards,
fasten the side rails with the screws. In the case of continuous side rails, the plastic caps may have to be pulled out
slightly so that they can be mounted.
Inserting the decorative foil into the telescopic posts
Take the decorative foil (1) and push it from below through
the slot in the plug (2) into the aluminium profile of the side
rail post (3). Please make sure that the correct side of the
decorative film is facing outwards. This will be difficult to
remove later. Push the decorative foil in until it is flush with
the button (4). On the lower plug (2) there is a snap-in lug
which prevents the decorative foil from falling out.
35
4.4 Emergency lowering - back part (standard)
In case of power or drive system failure, you
can lower the elevated back part manually.
Must be carried out always by two people!
One person lifts the back part slightly (to
take pressure off) and holds it in this position. As next step, the second person removes the locking pin from the motor.
The motor is now separated from the back
part and can be swivelled downwards.
Once the second person has left the danger
zone, the first person can lower gently the
back part.
Hold the back part by all means until it is
fully lowered.
Hazard note from Bock
Emergency lowering may be only carried out in an emergency by people who safely master this
operation.
Always disconnect the comfort / nursing care beds from the power supply as long as the motor
has not been remounted.
36
4.5 Emergency lowering - back part (optional)
In an emergency, the backrest can be lowered by means of a mechanical device on the
comfort/nursing care bed. To do this, move the red operating lever upwards in the direction of the head end piece. The speed of lowering depends on the weight of the mattress
and the weight of the patient.
Operation:
Hold the mattress bracket (1) on the backrest with one hand and move the red operating lever (2) upwards with the other hand in the direction of the head end piece (see arrow direction). The backrest moves downwards. Hold your hand on the mattress bracket
(1) until you release the control lever (2). The backrest will then be held in this position.
Make sure that the control lever (2) points vertically downwards again after the operation.
Hazard note from Bock
With heavy patients, the backrest can lower very quickly. Always lower the backrest with one
hand on the mattress bracket to check the adjustment.
37
4.6 Change of location
If the comfort/nursing care bed must be moved to another location, please follow these
safety instructions:
– Move the lying surface into the lowest position using the button (10) of the hand
control.
– Before conducting a movement, pull the mains plug and fasten it to the top of
the lying surface, in order to secure the power cable against falling down and
getting run over. Make sure that the cable is not dragged over the floor.
– Before inserted the mains plug again, inspect the power cable visually for me-
chanical damage (dents and kinks, abrasions and bare wires).
– Place the power cable in a way that it will not be rolled over by the comfort/nurs-
ing care bed, or strained during the operation of the comfort/nursing care bed,
or could become damaged when inserting the mains plug again.
– Carry out a reset run as described in chapter 3 "The hand control"

6 Cleaning, maintenance and disinfection
The individual bed elements consist of high quality materials. The surfaces of the steel
tubes is covered with a durable polyester-powder coating. All surfaces of the wooden
parts are surface-sealed with an ecologically coating that is low on harmful substances. All
bed elements are easy to clean and cared for using wipe and spray disinfection means
according to the applicable cleaning requirements with respect to the various areas of
application. Observing the following care instructions will retain the usability and visual
appearance of your comfort/nursing care bed for a long time to come.
6.1 Cleaning and care
Steel tubes and vanished metal parts:
Please use a wet wipe and a regular mild household detergent for the cleaning and care
of these surfaces.
Wooden-, decorative-, and plastic elements:
All standard furniture cleaners and cleaning detergents can be used. Using a wet wipe
without detergent additives for the cleaning of the plastic elements should generally be
sufficient. For care of the plastic surfaces use a product that is specifically suitable for
plastics.
Drive:
To prevent the intrusion of moisture into the motor housing, we recommended using only
a damp rag to clean outside housing.
Spring systems ripolux neo:
Use a damp rag without adding any detergents, or, if deemed necessary, a detergent that
is exclusively suitable for plastics and clean the spring elements made of plastics. In case
of heavy contamination, remove the spring elements from the supporting elements and
the supporting elements from the frame of the lying surface. The dismounted plastics elements can be rinsed or spray-washed with hot water to get them clean. For the disinfection, the components should be sprayed with a detergent suitable for plastics. Most of the
moisture drips off the plastic surface by slightly shaking it, while the rest will dry on its
own within a very short time. Remount the elements after they have completely dried. If
required, you can also remove each of the individual lying surface elements completely
from the frame to clean them.
41
Cover materials
Fundamentally, a regular cleaning will increase the service life of textile and imitation
leather covers. Particles not removed (dust, crumbs) can cause damage to the covers
through abrasions and chafing.
To clean the polyester covers, vacuum them regularly and occasionally wipe them with a
damp cloth or clean them with a high-quality upholstery shampoo. Adhering residues can
be removed with a soft brush or cloth. To clean stains, moisten them with warm water
and add a few drops of detergent liquid to the appropriate areas. Allow it to act briefly
and then brush or rub off the cover vigorously. If necessary, repeat the procedure several
times. Afterwards, rinse the cover with lukewarm water and rub dry with a cotton cloth.
To clean the artificial leather covers, use warm and mild soapy water, and a soft, lint-free
cloth or hand brush. In case of heavy soiling, rinse the area with fresh water and dry it
with a soft cloth. If any existing stains do not disappear, you can generously apply a solvent-containing cleaning agent to the stain with a soft cloth or sponge. Afterwards, rinse
again with fresh water and dry with a soft cloth. The use of plastic cleaners is not recommended.
6.2 Disinfection
Disinfect the comfort/nursing care bed with a wipe-on disinfectant. Please adhere to the
tested and recognised procedures of the Robert Koch Institute (RKI). You can use commercially available cleaning and disinfecting agents approved by the RKI. In order to maintain the material resistance of the plastic elements such as the motor housing and decorative elements, only mild and gentle agents should be used for disinfection. Concentrated
acids, aromatic and chlorinated hydrocarbons as well as detergents containing highly concentrated alcohol, ether, ester and ketone may damage the material and should therefore
be avoided. The list of disinfectants and disinfection methods tested and approved by the
Robert Koch Institute can be found on the Internet at www.rki.de.
6.3 Avoidance of hazards
In order to avoid dangers in connection with cleaning and disinfection, you must first observe the following regulations in connection with the electrical components of your comfort/nursing care bed. Non-observance of these guidelines may result in considerable
damage of the electrical lines and the drive.
1. Pull the mains plug and position it in such a way that contact with excessive
amounts of water or detergents can be excluded.
2. Check all plug-connections for correct position according to the instructions.
3. Check the cables and electrical component parts for damage. Should you detect
any damage, do not perform any cleaning operations but first have the defects
repaired by the manufacturer or an authorised/ licensed electrician.
42
4. Before starting the operation, check the mains plug for residual moisture and dry
or blow out the device, if necessary.
5. On any suspicion of the intrusion of moisture into the electrical components, dis-
connect the mains plug immediately and do not re-establish the connection. Put
the comfort/nursing care bed out of operation immediately, attach an appropriate visible label and contact the operator.
Hazard note from Bock
Use of abrasive cleansers and/or detergents containing grinding particles, cleaning pads or stainless steel cleaners for the cleaning is absolutely not recommended. Neither use organic solvents
such as halogenated/aromatic hydrocarbons and ketones nor detergents containing acid or alkaline.
Never clean the comfort/nursing care bed using a water hose or high-pressure cleaner as this
might lead to the intrusion of fluid into the electrical component parts, which could then cause
malfunctions and hazards.
The comfort / nursing care bed must be cleaned and disinfected before each use. Also, at the
same time, perform a visual inspection to check for any mechanical damages. You will find detailed information on this in the inspection list.

The medizinisches Bett is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the medizinisches Bett can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the medizinisches Bett as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above the recommended separation distance d in metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and
people.

8 Regular inspections with service
Regular inspections facilitate the maintaining of the highest possible safety level, and are
considered to be an important safety precaution. Medical devices must be inspected regularly in terms of safety according to the stipulated regulations of the manufacturer and
the generally accepted rules of technology. The safety-related protection measures are
subject to different requirements and demands. This also applies to the potential wear
and tear in the daily use. To prevent such risks, constant and consistent compliance with
the deadlines for regular functional testing is absolutely necessary. The manufacturer has
no influence on the operator’s adherence with respect to the observance of these regula-
tions concerning electric beds. Bock facilitates the observance of the necessary precautionary measures to be taken by means of their time-saving services.
The execution of the inspection, assessment and documentation must be performed only
by or under supervision of professional persons such as electricians or electro-technically
instructed persons who have a thorough knowledge of the relevant provisions and are
able to recognize possible impacts and hazards.
In the event that no person on the part of the user is eligible for the regular inspections
or is commissioned, the Bock service offers you the assumption of the regular inspections
with simultaneous control and observance of the corresponding intervals for a fee.
The company Hermann Bock GmbH specifies an inspection interval which stipulates that
a safety-technical inspection is to be executed at least once annually, and with each reuse of the bed.
For support purposes, Hermann Bock GmbH will provide you with the inspection list in the
assembly and operation manual for carrying out all the necessary tests. Please copy the
checklist as a form for your inspection. The checklist serves as evidence report of the performed inspection and must be kept on file.
The inspection list can also be downloaded from the Internet: www.bock.net.
Attention: Unauthorised technical changes to the product voids all warranty claims.
